POCUS - Thoracic Sonography in Times of Corona: What Sonographing Family Physicians Should Examine Abstract. When performing chest sonography of patients with symptoms such as respiratory infection, dyspnea and chest pain, the primary goal is to find or exclude significant diagnoses such as pneumothorax, pleural effusion, pulmonary edema, tumors, pulmonary emboli, etc. as the cause of the symptoms. If infection with SARS-CoV-2 is present, COVID-19 pneumonia can be confirmed or excluded as the cause of the symptoms with a high degree of probability based on the sonographic signs. COVID-19 pneumonia shows typical changes in the lungs, which are easily accessible to ultrasound due to their usually peripheral location. These are ubiquitous signs, such as a thickened, fragmented pleura with subpleural consolidations, multiple comet tail artifacts of varying size and thickness, some of which are coascent, broad bright light beams, and possibly small encapsulated pleural effusions. The more of these sonographic signs are present and the more pronounced they are, the sooner the patient must be hospitalized and possibly intubated. Ultrasound is also useful as a follow-up tool, together with clinical and laboratory findings.
